HINGE.

SPEGIFICATION forming part of Letters Patent No. 517,124, dated March27, 1894.

Application filed May 31, 1893.

To 00% whom it may concern.-

Be it known that I, JOSEPH NICHOLS, acitizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Hinges, of which the followingis a specification. I

My invention relates especially to the class of hinges used for triplemirrors, used by gents furnishing houses, and is especially designed foruse where it is desired to swing the hinged article through as large anangle as possible, and clear the post or fixture to which the hinge isfastened.

Reference will be had to the accompanying drawings in which- Figure 1 isa side vertical view of a mirror hinged to a post. Fig. 2 is a frontView of one hinge and post, the mirror removed, showing the shank of thehinge in section. Fig. 3 is a top plan view of the hinge with the shankof the hinge in dotted lines, and the pivot points of the 'shank insection. Fig. 4 is a side sectional view on the line 4. 4. Fig. 2. Fig.5 is a bottom plan view of the shank of the hinge. Fig. 6 is a sidesectional view on the line 6. 6. Fig. 3.

In the drawings -A- designates a mirror to which there is attached theshanks G of the hinge, the body of the hinge D being fastened to post B.To the shank O of the hinge, there are fixed pivot pins 0 O O 0isshorter than O and 0 for the purpose of clearing the fins D, as willbe described later, and O and (l are provided with slots O to engagefins D'.

In the main body of the hinge D there is a guideway 02, which engagesthe pivot pin 0 during a part of the revolution of the hinge, whichguideway is shaped to conform to the movement of the shank when guidedby the pins 0 and 0 when in engagement with fins D', and also to guidethe shank in conjunction with either pin 0 or C alone, when the same isover and revolving on the center of studs D or D until the position ofthe flange d or 01 is such as to hold the pin 0 or C in position withoutthe aid of pin 0 In the body of the hinge D there is pivoted at thepoints at (Fig. 6) two studs Serial No. 476.069. (N 0 model.)

jections 6', e shown, in dotted lines in Figs. 2 and 3, whichprojections e e engage the notches e in the flange D of the studs D DTwo of the notches e are shown, one is to hold the stud in position sothatthe flanges 01 d will be in line with the fins D and the other oneis to steady the mirror in a position at which itis frequently used, andthus a number of, such notches may be made in the flange D to' suit thecases required. The fins D are cut away at d to permit the pins 0 (3 topass out at the period of the revolution when one of them centers on thestuds D D The operation of the hinge from the central position shown inthe drawings is thus, in moving in either direction the pins C G withtheir slots O ride on the fins D, and the pin 0 moves in slot d, whichconforms to the movement produced by the fins D, and when one pin say 0centers over flange d of stud D as it ceases to move farther in the lineof fin D, but turns on the center of stud D which move ment turns thestud also as slot 0 engages flange d and the shank C revolving on thepivot D revolves pin gagement with fins D' through the space (1 and thepin 0 clears slot d and passes out over fin D, and the revolution of thestud D prevents the disengagement of the pin 0 and the flange d of thebody D sustains the outward strain of the pin 0 This is shown by thedotted position C Fig. 3. wherein 01 indicates the position of flange dThus this hinge makes possible almost a complete revolution and at thesame time clears a space wherein a post may stand to sustain the hingedarticle.

What I claim is 1. In a hinge the combination of the body D formed withthe guideway .d, the revoluble studs D and D seated therein 0 out ofennear the inner edge and on opposite sides thereof, and the curved finsD' on its outer edges, of the shank having pin 0 to engage saidguideway, and slotted pins C and C on the inner end and opposite sidesof said shank to engage said fins, whereby the guideway 01, pins G finsD', pins C and C sustain and carry the shank through the central portionof the revolution, while studs D and D carry the said shank during thebalance of the revolution, substantially as, and for the purpose shownand described.

2. In a hinge the combination with the body D provided with tworevoluble stud pivots D D at the sides thereof, and having flanges d dof shank 0 having pins adapted to engage said studs, during a part ofthe revolution of the hinge, of an independent carrying device forcarrying the shank of the hinge through the period of revolution,clearing the space occupied by the sustaining post for the purposeshown.

3. A hinge having a shank 0, having pins C and G at the inner end andopposite sides thereof, a body D having revoluble studs D and D at theopposite sides thereof, said pins 0 and G engaging the studs D and Dthrough parts of the revolution of the hinge, substantially as shown anddescribed, combined with a spring engaging locking device to hold thegaging the studs D and D through 40 parts of the revolution of the hingesubstantially as shown and described, combined with a spring engaginglocking device to hold studs D and D in position for the purposedescribed; said locking device consisting of a flange D on said studshaving notches e, a spring catch E engaging said notches as shown.

5. A hinge having a shank 0, having pins 0 and G at the inner end andopposite sides thereof; a body D having revoluble studs, pivots D and Dat the opposite sides thereof, and flanges (1 outside of said studscombined and arranged substantially as shown, and for the purposedescribed.

In witness whereof I have hereunto subscribed my name in the presence oftwo witnesses.

JOSEPH NICHOLS.
